PROBLEM TO BE SOLVED: To provide a dye-sensitized solar battery module having a high power generation efficiency.SOLUTION: A dye-sensitized solar battery 1 comprises, in an electrode cell, a transparent conductive substrate and a plurality of porous power generation layers. The plurality of porous power generation layers are arranged in different locations on the transparent conductive substrate, creates a contrast between the different locations when viewed from a light-receiving surface 2a, and has geometric shapes respectively. The dye-sensitized solar battery 1 further comprises, in the electrode cell, contour layers. The contour layers form, at boundaries between the different locations, contour parts of geometric shapes that the porous power generation layers have when viewing the dye-sensitized solar battery 1 from the side of the light-receiving surface 2a. The contour layers are different from the porous power generation layers in reflectance by 40% or more, and lower than the transparent conductive substrate in resistance value, and serves to transmit electrons generated by the porous power generation layers to external connection electrodes. |
